Paver Calculator
Calculate paving stones to buy from patio size, actual paver dimensions and cut allowance.
Choose the worksheet for your task
- Identical stones: pieces and packsUse actual dimensions and the number of identical stones in a required pack.
- Mixed sizes sold as a pattern packUse matching supplier coverage, separate the border and compare whole-pack cost.
These are independent worksheets. Inputs do not transfer between them. Use the download button beside the result you want to keep.
- Project area
- 192 sq ft
- Order area with waste
- 211.2 sq ft
- Pavers needed before pack rounding
- 951 pavers
- Required purchase units
- 951 single pavers
- Packaging surplus beyond allowance
- 0 pavers
- Material subtotal (entered price only)
- Not supplied
Purchase quantity includes whole-pack rounding after the cut allowance. Packaging surplus is separate from that allowance. Price is per individual paver, not per pack; divide a pack quote by its paver count first. This is a single-size area estimate, not a laying plan.
Whole packages round up. Prices include only the items you enter. Delivery, tax and installation may be extra.
Mixed-size paving: order by pattern-pack coverage
A pack containing several stone sizes cannot be represented by an average stone width. Use the supplier’s square feet per complete pack for your selected pattern. This worksheet is independent of the identical-stone calculator above.
Read the quote before calculating
- Identify whether coverage and price are for one layer, one bundle or a full pallet. Both must refer to the same required purchase unit.
- Confirm the listed coverage applies to your pattern and joint spacing. Do not add joint area again if it is already included.
- Measure the field and any different-product border separately. Subtract the border only if it is inside your total paved area. Estimate border stones separately using their actual layout.
- Choose a cut allowance for the layout. Pack surplus is not proof that every leftover size can be used at an edge; confirm the supplier’s pattern diagram and size mix.
Why cheaper square-foot pricing can cost more
Hypothetical project: 240 sq ft including a separately purchased 24 sq ft border. The pattern field is 216 sq ft; 7% cutting allowance makes 231.12 sq ft. Offer A covers 100 sq ft per pack at $240: 3 packs cover 300 sq ft and cost $780 including $60 delivery. There is 68.88 sq ft of packaging surplus beyond the allowance.
For an equally suitable pattern product, Offer B covers 80 sq ft per pack at $210: 3 packs cover 240 sq ft and cost $690 with the same delivery. B costs more per nominal square foot ($2.625 versus $2.40) but saves $90 on this order. Load A, download its record, then change coverage to 80 and pack price to 210 to compare B. These are invented quotes, not current market prices or interchangeable product recommendations.
For A, a quote priced per square foot of purchased pack coverage would be $720 ÷ 216 = $3.3333 per installed field square foot before delivery, not $2.40. Do not enter the pack price as a price per single stone or count the border twice. For the remaining materials use the patio materials worksheet, whose paver line assumes identical stones: keep its paver subtotal separate and replace that line with this pack order rather than adding both.
How to calculate
This area method assumes a single rectangular paver size. Joints are not deducted, making the count conservative. Mixed-size patterns need the manufacturer’s pattern coverage.
Worked example
Length (ft): 16 · Width (ft): 12 · Paver length (in): 8 · Paver width (in): 4 · Pavers per required pack (1 = singles): 1 · Extra material (%): 10.
These inputs produce 951 pavers to order. Change the measurements above to match your project.
Measure the right surfaces
Measure only the paved surface and use actual unit face dimensions. A border made from a different stone needs its own count. For a mixed-size pattern sold in bundles, obtain square feet per bundle instead of treating all stones as one rectangle. Joint space is not removed by this calculator.
A second example you can check
A 10 × 12 ft rectangle has 120 sq ft. An 8 × 4 in stone has 32 sq in, so the area-only count is 120 × 144 ÷ 32 = 540 stones. A 7% cut allowance gives 577.8, rounded up once to 578 stones. Set Pavers per required pack to 100: the tool returns 6 packs, 600 purchased stones and 22 packaging-surplus stones beyond the 578 requirement. At a hypothetical $200 per pack, enter $2 per paver; the material subtotal is $1,200, not $1,156. These prices illustrate the calculation, not a market quote. Keep the pack input at 1 only if singles are sold.
Where estimates go wrong
Area arithmetic does not produce a laying pattern. Diagonal cuts, a narrow edge course or a change in orientation can consume whole stones even when the removed pieces have substantial area. Reusing every offcut is an assumption to check, not an assured saving.
Build your supplier order
Bring the intended pattern and border layout to the supplier. Confirm actual dimensions, pieces per bundle, color batch, breakage policy and whether spare stones can be bought individually. Check base, bedding, edging and jointing materials separately.
Paver: practical questions
Why might this count exceed the layout count?
The calculation ignores joints between units. That conservatively treats the whole surface as stone; a drawn layout can be more precise.
Should I round each small area?
Combine areas for identical stones before final rounding. Separately rounded rectangles can add unnecessary pieces.
